My ADHD husband has told me, "I keep things inside me, even though I'm really upset about something, but you have a harder time doing that". This doesn't make sense to me, because I believe that open communication is the key to a good relationship, not "keeping it all inside". I don't nag or yell at him about things, I've never been a nag, because I don't like that, but he REALLY has a hard time when I want to openly discuss something. He can talk for hours on lots of other things, but when it comes to US, he totally clams up. I don't understand.
